Feigning sophistication about cuts of steak has always been challenging (“The Delmonico… or maybe a Kansas City Strip?”), and that was before  steak-house menus started looking like a U.S.D.A. licensing exam. These days you’re forced to make decisions based on a steer’s feed, breed, and nationality—decisions, you’re told, of some importance to your dinner. Grain-fed or grass-fed? Is Wagyu worth the hedge fund-size investment? Should you pay by the day for dry aging?

Skeptics see all the fuss as needless complexity and snobbish marketing, and blame an increasingly competitive restaurant industry for the phenomenon. “Everyone’s trying to differentiate themselves, and making so many distinctions helps them separate from the crowd,” says Jody Storch, a member of the family that owns Peter Luger Steakhouse in New York City. Apologists say savvier diners deserve, and demand, all the details. Tom Colicchio, chef-proprietor of the family of Craft restaurants and star of the television show Top Chef, was an early proponent of the full-disclosure menu approach, which he has extended to both of his CraftSteak steak houses. “People want to know where their food comes from,” explains Colicchio. “We’re just providing them with the information.”

No matter what side you’re on, complicated menus have become nearly impossible to avoid. So how can you sift the key facts from all the… well… bull? Try these seven tips for finessing the field.

Look for prime. A basic designator of high-quality meat, prime is the U.S.D.A.’s top grade (followed by choice and select), representing less than 5 percent of the beef sold in the United States. The grading system is largely based on “marbling,” or how fat is distributed throughout the muscle, explains Dave Zino, executive director of a consumer division of the National Cattlemen’s Beef Association. “The better the marble, the higher the grade, the tastier the steak you end up with.” Just know that a restaurant can call itself a “prime steak house” if it offers even a single cut of prime-grade beef.  

Natural or organic? These terms are used inconsistently and sometimes interchangeably on menus, but an “organic” cut signals that the steer was raised on pesticide-free feed. That might please the environmentalist in you, but it’s not likely to have an impact on the taste of the beef. Antibiotics and hormones (also excluded in organic meat) are a different story. “When hormones are given to cattle, it speeds up their growth. This makes them cheaper to raise, but also leads to tougher, blander meat,” Colicchio explains.

Do I want old meat? Many chefs agree that dry aging—hanging a side of beef in a humidity-controlled cooler for upwards of three weeks—is essential to a dynamite steak. Meat is tenderized in the first two weeks. After that, dehydration concentrates the flavor into a rich, pungent beef taste. Why do you pay more? Aged meat can lose almost 20 percent of its weight to evaporation. Storage space, cooling costs, and the butcher’s attention also contribute to the price. While there’s no consensus about the “right” aging time, 14 days is generally the minimum; 21 to 28 days is standard. Colicchio thinks the “sweet spot” is around six weeks—at which point the flavor is rich but not gamey or musty. Jason Miller, executive chef at Chicago restaurant David Burke’s Primehouse, touts a state-of-the-art aging box that can safely hold beef for up to 60 days.

Grass- and grain-fed do taste different. But one is not better than the other. “It’s totally a matter of taste and mood,” Zino explains. All cattle eat grass for the majority of their lives, but grain-fed animals are “finished” in feedlots. Grain feeding, traditional in the U.S., produces fattier, richer-tasting meat. Grass-fed cattle, once imported from Argentina and other countries, yield a leaner, chewier beef. In grocery stores, grass-fed beef typically commands higher prices than grain-fed. However, since the grain-fed offerings in steak houses are superior in quality to those at the store, the entrée prices of grain- and grass-fed choices tend to be similar.

Ask for advice on cuts. There are so many ways to subdivide a steer that even aficionados have trouble keeping up. Plus, many cuts of beef have multiple names (tenderloin equals filet mignon equals chateaubriand). In high-end steak houses, you’ll mostly find meat from the rib, short loin, and sirloin areas, which provide recognizable cuts like strip, rib eye, filet mignon, and porterhouse. The owners of Peter Luger prefer the porterhouse because it’s a combination of an aromatic, juicy strip and a lean, super-tender filet mignon (a T-bone is a porterhouse with a smaller filet portion). Star chef and restaurateur David Burke, one of the men behind Smith & Wollensky, is a sucker for the hearty, heavily marbled rib eye.

What’s Wagyu? Rich and devilishly expensive, Wagyu beef, named for a breed of Japanese cattle, is the meat fad of the moment (Kobe beef comes from those Wagyu raised in Kobe). Wagyu cattle are raised to maximize marbling. The amount of time and the sheer volume of feed required means much higher costs for the rancher and a premium at the table. Chefs liken Wagyu to other culinary luxuries like caviar and foie gras—worth the price, but meant to be eaten sparingly. Health nuts may want to avoid the heavily marbled (read: high-fat) meat altogether.

Know what to ignore. State or country of origin won’t tell you anything about the quality of the cattle. There are innumerable high-quality cattle ranches and farms; unless you’re an agricultural expert, you shouldn’t expect to recognize their names on a menu. And feel free to ignore aging time: Once you get beyond three or four weeks, the proper aging period depends on the piece of meat.
